【 摘 要 】

The linear long-wave theory is used in the first stage to find the tsunami initialprofile. The perfect reflection is assumed at the land boundary. On comparing thecomputed with the measured overall runup distribution, the best fault model is foundamong 24 models. It consists of three sub-faults dipping westward. It satisfies themeasured land subsidence and overall distribution of runup heights in Okushiri Island.Then, the shallow-water theory with bottom friction is used to simulate runup.The runup condition is used as the land boundary condition. The arrival time andrunup heights agree well with the measured.
